Wales have won the Triple Crown in the Six Nations tournament after beating Ireland 16-12.
Ireland were leading 6-3 at half-time, but Wales dominated after the break with wing Shane Williams breaking through to score his 40th Test try.
Shane Horgan came closest to an Irish try, but the hosts couldn't stop Wales beating them at their home ground in Dublin for the first time since 2000.
Wales now face a Grand Slam decider against France in Cardiff on 15 March.

Elsewhere, Scotland got their first win of the 2008 tournament as they battled against England in a wet and windy clash at Murrayfield.
Chris Paterson's kicks gave Scotland a deserved 9-3 lead at the break and two later penalties secured their 15-9 victory.
It wasn't all bad news for England though. Jonny Wilkinson's penalty in the first half saw him become rugby's top international point scorer of all time.
He carried on scoring after the break, but it wasn't enough to defeat Scotland.
